Great efficient PSU

I bought an LGA 1700 B610 firewall appliance that had a cheap flex PSU in it so I decided to replace it with this. Replacing it cut my idle power wattage by at least 15W, and 30W under 20% load. Great tiny PSU powering an i5-14500T.

SO quiet

Replaced noisy stock ITX case PSU with this Flex ATX 500W and am super happy with how quiet it is.I noticed the PSU I replaced had its fan on the outside near the power blade, whereas this PSU has the fan internally to the outside of your case, so, even mutes the already quiet fan dB level even more.I would give this PSU 6 stars if I could.

Fan speed might go crazy. Keep your warranty info.

I've bought two of these. But, the last one that I purchased in Feb 2025 suddenly started to have "fan control" issues two months, later.The cooling fan started to spin like crazy out of control and became too loud.This PSU was doing fine until that time.The first PSU from Jan 2025 is fine, so far.

High Quality - Flex Guru 500W

ITX / ATX Flex Guru 500W - Very good PSU.NOTE: You may need SATA to Molex adapters if additional fans are used.

A good power supply

I tried it , it works properly, but I was wishing it to be a modular for easy installation.
